SPECIFICATION, forming part of Letters Patent No. 734,901, dated July 28, 1903.

To dZZ whmm it may concern: i

Be it known that I, BRADFORD LESLIE, K. C. I. E., a citizen of England, residing at The Moat, Harrow-on-the-Hill, in the county of Middlese'x, England, have invented a certain new and useful Apparatus for Measuring Coal or the Like, (for which I have applied for a patent in Great Britain, dated November 5, 1901, No. 22,292,) of which the following is a specification.

My invention relates to a measuring-wheel for coal or likematerial which delivers the coal automatically in measured quantity into conveyer-buckets or the like, as I will describe with reference to the accompanying drawings, in which- Figure 1 is a vertical longitudinal section through the hopper and measuring-wheel, and

Fig. 2 is an end elevation thereof.

. The measuring-wheel ahas in its periphery anumber of pockets b. The axle c of the wheel is revolved in the direction of the arrow, Fig. 1, by any suitable motor, and as each pocket passes beneath the mouth of the hopper d it is charged with coal. To insure a satisfactory discharge of coal by gravity from the hopper, its chute d is hinged at (1 and on the framing which carries the hopper is a stopd Each pocket b has a steel bracket b, havinga knife-edge forwardly projecting inthe direction of rotation of the wheel. As the wheel revolves this bracket engages with shoulders on the sides of the chute d, as shown in Fig. 1, thus raising the chute until in the course of-its travel the bracket 1) is free of the said shoulders, whereupon the chute falls back onto the stop d and there is a sudden discharge of coal into the next succeeding pocket. Since the pocket passing beneath the chute is liable to become overcharged, a plow e is fixed to the casing of pocket-wheel, and on each side of this are side chutes e, which convey the coal rejected by the plow from the overcharged pocket into the next succeeding pocket or pockets. The

steel edges of the plow and of the buckets b being sharp, any lumps of coals which are of such shape that they do not ride over the plow are broken or sheared between these edges and the side of the wheel. v

The measuring-wheel is covered by a fixed casing f except at that part where the pockets pass'the side chutes of the plow and the hopper and at that part where the pockets in the course of their revolution discharge themselves into the conveyor-buckets or the like.

Having thus described the nature of this invention and the best means I know of carrying the same into practical effect, I claim-- 1. In combination, a measuring-wheel having pockets in its periphery, a projection on each pocket, a hopper, and a chute hinged to the hopper and having its bottom wall extending throughout at an inclination, said chute adapted to extend in the path of the said projections and to prevent the sticking of and to insure a discharge of the coal from the hopper. I

2. In combination, a measuring-wheel having pockets in its periphery, a plow so fixed in relation to the wheel that it rejects overcharge of material from the pocket that has been charged, chutes adapted to receive and conduct such overcharged material into the next succeeding pockets, a knife edged bracket on each pocket projecting forwardly in the direction of rotation of the wheel, and

arranged to pass immediately beneath the when released from the bracket.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
